I have tested the new series on rk3588 and rk3399 with chromium. Since the
HEVC decoder need EXT_SPS_RPS related patches, I ony test the H264 decoder.
There are two issues:

1, The decoder max size is detected 1920x1088, which should be the fallback
size when queryig VIDIOC_ENUM_FRAMESIZES[1].

2, Playing H264 videos ends up with green screen.

These above issues don't happen with the old rkvdec2 series.
